摘要

建立了带有硅树脂光学元件的片上封装发光二极管阵列的仿真模型。仿真的原理是通过调整光学元件的形状和尺寸来获得最大的光输出功率，研究光学元件特征对光提取效率的影响。由于圆柱形树脂基光学元件在COB封装LED产品中很常见，因此在仿真中选择并优化了这种几何形状。此外，应用微透镜阵列进一步提高了性能，发现这种设计是提高LED LEE的有效途径。

Modeling and simulation of LED optical component to enhance light extraction efficiency

A simulated model consists of chip-on-board (COB) packaged light emitting diode (LED) array with silicon resin based optical component was built. The principle of the simulation was to investigate the roles of optical component feature play in light extraction efficiency (LEE) by adjusting shape and size of the component to obtain maximum optical output power. Since cylinder resin based optical component is commonly seen in COB packaged LED product, such geometry was chosen and optimized in the simulation. In addition, micro lens array was applied to further improve the performance and it has been found that such design is an effective approach to improve LEE of LED.
